Trocar-assisted flanged transconjunctival intrascleral sutureless intraocular lens fixation

To study the safety and efficacy of 25-gauge trocar-assisted flanged intrascleral sutureless IOL fixation in patients with insufficient posterior capsular support.

Five aphakic eyes with capsular insufficiency were included in this prospective interventional case series study, at Dar El Oyoun Hospital, Cairo, Egypt. Twenty five-gauge trocar-assisted flanged intrascleral sutureless technique was used for IOL fixation, in which retinal microforceps were used to capture and externalize both haptics through a scleral tunnel. CDVA, IOP measurements and IOL centralization were reported pre- and one day, one & 3 months postoperatively. Any intra- or postoperative complications were recorded.

The mean LogMAR CDVA had significantly improved one day, 1 & 3 months postoperatively (0.74 ± 0.1, 0.42 ± 0.07 and 0.26 ± 0.08 respectively, p < 0.001) compared to the preoperative value (1.7 ± 0.17). The mean IOP showed no significant changes along the follow-up period (16.9 ± 0.1; 16.2 ± 1.1; 16.3 ± 0.9 mmHg, p = 0.68, 0.58, 0.89) respectively at 1^st day, 1 & 3 months postoperatively) compared to the preoperative measurement (16.4 ± 1.8 mmHg). The IOL was found to be centralized in all cases. No intra- or postoperative complications were encountered.

25-gauge trocar-assisted flanged intrascleral sutureless IOL fixation is found to be a reliable and effective technique that overcomes Yamane technique's challenges for IOL fixation in cases with posterior capsular insufficiency.
